William CHAUMET (1842-1903). Autograph musical manuscript signed, Mamzelle Pioupiou, [1889]; 245 oblong fol. pages in 10 titled folders. Orchestral score of this music for Alexandre Bisson's (1848-1912) military spectacle play in 5 acts and 8 tableaux, premiered at the Porte-Saint-Martin theater on May 31, 1889, with Félicia Mallet in the title role. The play opens in Falaise, where Papillon, an unsuccessful acrobat, becomes the father of a girl named Marcelle, while pharmacist Maloisel has a boy named Camille on the same day; but the town hall employee makes a mistake and reverses the sexes. Twenty years later, when Papillon has left Falaise to seek his fortune in Tunisia, a gendarme comes to fetch Marcelle Papillon for service; although she could protest her gender, she gives in, to follow her lover Camille Maloisel, who has enlisted. In Tunisia, Marcelle (Mamzelle Pioupiou) rescues her father from the clutches of a mistress; she finds her own mother, who had been kidnapped and transported to the harem, takes part in the capture of Sfax, and ends up marrying Camille.
